It has been suggested that the Lees-Haley Fake Bad Scale (FBS) is effective in detecting malingered PTSD symptoms; however, earlier studies have failed to investigate the efficacy of the FBS in a sample of participants who are expected to experience trauma-related stress, but one in which compensation for symptoms is uncommon. Therefore, the current study utilized a sample of 21 non-litigating, sheltered, battered women reporting PTSD symptoms and compared their FBS scores to a matched group of compensation seeking women. Results indicated that the FBS appears to sufficiently detect genuine from spurious PTSD symptoms. Furthermore, PTSD symptom severity did influence FBS elevation in both groups. However, a considerable portion of the battered women were classified as invalid over-responders by the FBS. Nevertheless, the compensation-seeking group failed the FBS significantly more often than the non-litigating group. Limitations of the study are explored and directions for further research are provided.
